She has a brilliant resume, but she has been repeatedly frustrated in her career change activities.The interviewer repeatedly asked her why she left her job, and she always answered "for career".However, there are almost no companies with more status than Mitsuhashi Corporation, and even headhunters have a headache about her whereabouts.

One day, Kaoru unexpectedly received a call from Hidaka Moamie (Rina Kawaei), the president of **RAINBOW LAB Company. Although she had not originally passed the company's interview, Moami offered that she could serve as her daughter's tutor.
